So ive got some 18s ive been trying to sell, but i might just throw them back on the car. but they need some tires

they have Prada Spec2 215/40zr/18 85w which i cant find anywhere. the only comparable tire ive found was like 170+ a piece

anyone know what kind of tires i can get for cheaper? dont care much about grip for now. just need some tires! heh

-thanks
